We offer different types of MDF sheets for various applications which can be cut to any size or shape using our CNC router for a high level of accuracy and duplication. Whatever shape you have in mind, we can cut it – all you need to do is send us your drawings, in either CAD format or a sketch, and we can create it for you. Our CNC router can be used for rebating, pocketing and hole cutting on MDF sheets, as well as virtually any other sheet material. There is also the option to add laser cutting, CNC engraving and mitred edges to your MDF sheeting.

Using state-of-the-art UV printers, we can print full sheets of MDF in one go, providing a consistent finish at a much faster rate than painting. We currently only list 8x4 sheets (2440x1220mm) but we’re able to purchase and cut sheets of up to 2000x3000mm, so get in touch with our team today to discuss your requirements. With optional next day delivery, your products can be with you fast. For bigger orders, we have our own transport service which operates throughout most of the UK. If you have a larger ongoing project taking place, you can contact us to discuss bulk discounts and regular supply orders. 

Strong and resilient, 12mm moisture-resistant MDF sheets are the ideal board to use in environments which are prone to humidity and high moisture levels. Compared to standard MDF, the moisture-resistant MDF sheets, also known as MR MDF, contain a moisture-repellent resin which provides a greater resistance to humid conditions. Moisture-resistant MDF is a premium-grade product that is designed for interior environments that are prone to humidity and damp. We provide custom-cutting services for our 12mm moisture-resistant MDF sheets so you can order your product to arrive in any size or shape you require. With a fast turnaround time and quick delivery, you will be able to make use of your MDF sheeting as soon as possible.


12 Moisture Resistant MDF Uses

There are several different varieties of MDF, depending on the application you’re using it for.

  • Moisture-resistant grade MDF can be used in areas of homes or businesses where moisture or humidity is an issue, such as bathrooms, kitchens or storage areas.


Advantages of 12mm Moisture-Resistant MDF

Moisture-resistant MDF shouldn’t be mistake for being the same as water-resistant wood, as it’s still prone to swelling and warping if it comes into contact with water. However, it is an incredibly useful and durable material with many benefits. MR DF is easy to fabricate and fix into place with glues, screws or nails, and it can be cut to suit different shapes and sizes on-site if need be. Because of the smooth surface texture of MDF, it’s the ideal substrate for painting and sealing with varnishes or stains, or even using veneers and laminates, and the light surface makes marking up the materials really easy.

An added benefit of using moisture-resistant MDF is the environmental impact it has. MDF is made up of recycled offcuts, wood chippings and sawdust that would otherwise be discarded. Different manufacturers will list how much recycled material makes up their product but MDF is largely considered to be a green and environmentally-friendly product. MR MDF is a great material choice for any application that is situated in a humid environment, as it will withstand the conditions without losing its structural integrity. 12mm moisture-resistant MDF is sturdy and durable and is suitable for use with all woodworking machines or hand tools. The consistent machining characteristics make it ideal for high-quality surface finishes to any application. We also offer fire retardant MDF.


Applications of 12mm Moisture Resistant MDF 

Moisture-resistant MDF is best-suited to applications such as cabinets, window frames or boxing in pipes in kitchens or bathrooms. It can be used to great effect in boiler rooms or laundry and utility rooms, as well as cubicles and washrooms. This variety of MDF is also popular for shop fitting, bars and for general joinery. The moisture-repelling resins in this material make it a superior product in comparison to standard MDF for these types of application. It can be cut and manipulated with the use of hand tools and power tools and is easy to sand down for a smooth and professional finish which also prevents harmful fibres from being released. We also offer 9mm MDF and 15mm MDF.

Frequently Asked Questions

What tolerance do you cut to?

We cut to a tolerance of +/-1mm.

What is your delivery timescale?

3-7 working days.

Is mirrored acrylic like normal mirror?

Mirrored acrylic is a flexible material, and needs to be attached to a perfectly flat surface. We recommend attaching it to MDF or something similar, making sure the adhesive is spread in a thin even layer across the acrylic. we also recommend using the 5mm thick acrylic as it is more rigid.

Can you cut any shape?

Yes, in acrylic. We will shortly be able to also cut any shape in polycarbonate as well.

What's your standard radius corner?

20mm, but we can cut to your requirements.

How many holes do I need in my acrylic?

1 per corner should be sufficient for smaller pieces. You might want to consider an extra hole in the middle if your sheet is larger.

Can I cut acrylic?

Yes, you can. Just take it slow and easy.

Can I put acrylic behind a hob?

Not if it is gas or electric. You need a gap of 5cm between an induction hob and the acrylic.

Do you fit the acrylic?

No, we don't. We do provide some templates which should help you to take your measurements. The acrylic is easy to install by any competent DIYer.

What's the difference between acrylic and Perspex?

Perspex is a brand name. It is the same as acrylic.

Ideal for what I required doing my project of fitting a full length wardrobe.


Priced fairly, good quality, exactly what I had wanted. As a base for my Doll's House it blends in with the same material it is built with. It finishes the whole appearance. Very pleased.


It's exactly what I needed.




Wood was cut to size and arrived very quickly and packed really well.
